Subject: Re: [dipal-discuss] WS-Addressing and WS-Policy

DIPAL would also work with the proposal to add "compositors" (http://lists.w3.org/Archives/Public/www-ws-desc/2004Jan/053.html) to WSDL 2.0's "Features and Properties", as those are Boolean combinators. A third option would be to use XACML's Boolean functions, as is done in the "XACML profile for web services" (WSPL) (http://www.oasisopen. org/committees/download.php/3661/draft-xacml-wspl-04.pdf). The development of such a framework is outside the proposed scope of DIPAL's charter. WS-Policy must be submitted to a standards group before it can be considered by any other standard. I personally think it would be great if the WS-Policy authors would offer to join with DIPAL to create a domain-independent standard for addressing both layers of policy expression. Such a standard could still leave room for domain-specific Assertions in addition, either to address Assertions that have already gained acceptance or to address future Assertions that are more complex than DIPAL can handle.
